Abstract

Selon un mode de réalisation de l'invention, un procédé mis en œuvre par une UPF configurée pour traiter des données sponsorisées dans un système de communication sans fil configuré pour prendre en charge un service de données sponsorisées comprend la réception d'un message de demande d'abonnement pour s'abonner à un service d'exposition d'événement d'UPF provenant d'une NEF recevant une demande de génération de facturation en provenance d'une AF configurée pour fournir le service de données sponsorisées, la réalisation d'une opération de surveillance de facturation sponsorisée sur les données sponsorisées fournies par l'AF à un UE sur la base d'informations comprises dans le message de demande d'abonnement, ainsi que la transmission d'un message de rapport d'utilisation pour les données sponsorisées à une CHF en charge du traitement de facturation, sur la base de l'opération de surveillance de facturation sponsorisée.
